TLE2141AIP

TLE2141AIP linear amplifier is a compact and cost-effective four-channel instrumentation amplifier, designed to provide gains from 1 to 4000 with a ±2.25V common-mode input range and excellent common-mode suppression of 80 dB up to 10 kHz. This makes it well suited to a wide range of applications, including basic sensor pre-amplifiers, instrumentation inputs, autocorrelating systems, audio noise and signal processing, and analog-signal conditioning.

This instrumentation amplifier works by combining the output signals of two operational amplifiers in series, within the same IC package. The first operational amplifier is connected in a non-inverting configuration, while the second is connected in an inverting configuration with a gain that depends on the resistor values attached to its inverting and non-inverting inputs. This configuration produces a differential output signal from the two op-amp outputs, which is then amplified and buffered. The gain is set by an external resistor network, and can be adjusted from 1 to 4000.

The unique feature of the TLE2141AIP linear amplifier is the ability to accurately track common-mode input signals over a wide range of input voltages. This is made possible by its low common-mode rejection ratio (CMRR), which measures the linear amplifier’s ability to reject changes in the common-mode voltage, without affecting its gain. The TLE2141AIP features an CMRR of 80 dB up to 10 kHz, with a ±2.25V common-mode input range.

The TLE2141AIP has a wide range of applications. Its low power consumption and wide range of gains make it suitable for pre-amplifying weak sensor signals, while its excellent common-mode rejection ratio make it ideal for use in autocorrelating systems. Its low noise levels are suitable for use in audio signal processing, and its precision gain setting makes it suitable for use in analog signal conditioning.

In conclusion, the TLE2141AIP is a compact, cost-effective linear amplifier with excellent common-mode rejection, low power consumption, and a wide range of gains. This makes it suitable for a wide range of applications, from basic sensor pre-amplification to audio signal processing and digital signal conditioning.
